The Osprey Hornet 32 Pack is ultralightweight and ultracool. The BioStretch harness and the spacer mesh back provide awesome ventilation, and the stripped-to-the-essentials design reduces the weight of the bag to an ultralight and ultrafunctional state. Various internal and external compression features keep your load stable and compact. The adjustable sternum strap and BioStretch hipbelt help transfer weight from your back to make for a comfortable carry.
